ADJUSTMENTS
ADJUSTING THE QUILL HEIGHT
The Quill (#27, Fig. 20, A) can be set to a particular
depth or position with the lower, Scale Nut (#31, B) on
the Depth Threaded Rod (#32, C). This nut is located
under the cast metal Depth Plate (Fig. 20, D).
1. Lower the Quill/Chuck to the depth that is desired
with the feed handles.
2. Turn the lower Scale Nut (B) up the Threaded Rod
(C) until it stops up against the Depth Plate (D).
3. Release your hold on the drill press’ feed handles
and the Quill with chuck will stay in the set position.

ADJUSTING THE DRILL SPEED
FIG. 21
The Drill Press motor MUST be
operating before changing the speeds is done,
or damage to the speed adjustment mechanisms
may result.
1. To adjust the operating speeds while the drill press
is running, rotate the Speed Handle Lever (#58, Fig.
21, C) until the desired speed is shown on the LED
display (D) on the machine front. FIG. 21.
- Move the lever FORWARD to increase speed.
- Move the lever BACKWARD for slower speeds.
This Drill Press has two
variable speed ranges from
150 to 700 and 600 to 2,800 RPM. To change from
one speed range to the other, only the rear Drive
V-Belt (#80) needs to be re-positioned on the pulleys.
2. Loosen the belt tension by moving the motor closer
to the head casting. Loosen the two Lock Knobs (#67)
and with 16mm wrench turn the motor plate’s leveling
Bolt (#137) clockwise towards the motor. Then pull the
Tension Lever (#89) forward to shift the motor mount
assembly forward. See page 10, Figures 6 & 7 for
photos identification of these parts.
3. Move the V-Belt on the rear and center pulleys to
set the drill press speeds as shown to the right;
- LOW SPEED - Belt is on the large, lower step on
the center pulley to the small step on the rear pulley.
- HIGH SPEED - Belt is on the small, top step on
the center pulley to the large, top step on the rear
pulley.
4. Reset the Belt tension by moving the motor back
from the head casting by reversing the steps in #2.
